Answer:
The first option.
Because we're solving for the price of each gallon, x will represent the cost of each gallon. Since 8.4 is the total amount of gallons, multiply 8.4 and x to get $23.94. Solve for x by dividing 23.94 to get $2.85 per gallon. To check this, substitute 2.85 for x into the equation: 8.4 (2.85) = 23.94

Answer:
Step-by-step explanation:
By looking at the graph I notice an open circle at (-4, -5) which means the function is not evaluable at -4, this restricts the domain.
The Domain of a function represents the set of values for which the function has an output.
The Range of a function is the set containing all the possible values associated with all input.
Domain in interval notation: (-4, 3]. The parenthesis denotes that the interval does not contain the extreme point -4. The brackets are the opposite.
Domain in set builder notation:
Range in interval notation: (-5, -3]
Range in set builder notation:
Answer:
Step-by-step explanation:
<u>Instantaneous Velocity</u>
Given r(t) as the vector function of the position for time t, the instantaneous velocity is computed as:
We are given:
Thus:
Computing the derivative:
Evaluating for t=π/4:
The answer to that question is N=3.
